Multi-wavelength observations of the flaring gamma-ray blazar 3C 66A in 2008 October
The BL Lacertae object 3C 66A was detected in a flaring state by the Fe r m i Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GAMMA, GASP-WEBT, PAIRITEL, MDM, ATOM, Swift, and Chandra provided radio to X-ray coverage. The available light curves...
